Home roof is a great place to put solar panels because it's virtually free space. Battery is different story.

  I mean the pics of this make batteries look pretty small. Like smaller than a storage shed. Sure it's only storing 8 hours, but the use cases described here are not bad. Imagine if we had 8 hours of battery storage across the world per household!

    Still it takes a bit space for non-rural Japanese houses. I agree it's good to have it for backup if free space is available.
